the fuse box is under neath the left side cover as in on the left side when you are setting on the bike it is the fuse that says signals i beleive it is a 15 amp fuse.

Hi There,
Got this from my copy of the Yamaha workshop manual for this model
The YZF-R1 features a self-diagnosing system for the following circuits:
1. throttle position sensor
2. EXUP
3. fuel level indicator light
if any of these circuits are defective their respective condition codes will be displayed on the tachometer when the main switch is set to "ON" (irrespective of whether the engine is running or not)
1. throttle position sensor a) Disconnected b) Short-circuit c) Locked 0 - 3,000rpm
2. EXUP a) Improper connection b) Short-circuit c) Servomotor is locked 0 - 7,000rpm
3. Fuel level indicator light a) Improper connection 0 - 8,000rpm
It looks like you have a problem with the EXUP Valve on yours, probably seized or maybe cables not moving freely
Hope this Helps

SOURCE: how much oil does a yamaha yzf r1 2007 take
"most" bikes on average without filter change take anywhere from 2.8 to 3.0 qts. I always purchase 4 quarts because an extra one will always come in handy in the future anyway. First your bike i believe has a sight gauge... First stand the bike upright on a stand or have someone hold it up for you pour in 2 and 1/2 quarts, put fill cap on, start bike, let warm up for about a minute to let the oil settle, then turn off and then start pouring in slowly till it gets to a little above 3/4 full on the sight gauge...you never want to overfill it could cause engine damage. Now just remember how much oil you put in and that is the approx. amount.
